Professional Applications & Engineering Value
This M6 flat head screw delivers critical performance in demanding applications where corrosion resistance and mechanical reliability are paramount. Manufactured from 316 Stainless Steel with a passivated finish, it withstands aggressive chemicals, marine atmospheres, and high-moisture conditions far better than standard stainless grades. The coarse M6x1 mm thread and Class 6g tolerance enable quick assembly and a secure fit in metals, plastics, and composite materials, reducing the risk of cross-threading. The hex drive and fully threaded shank ensure high clamp force is maintained, making it an ideal choice for machinery, structural fabrications, and outdoor equipment where long-term durability is non-negotiable.
Specification Summary & Compliance
This metric screw conforms to DIN 7991 specifications, featuring an M6x1 mm coarse thread with a Class 6g thread fit. The head diameter is 12 mm with a tolerance of -0.43 to 0 mm, and the overall length is 40 mm. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and safe for use in industrial and consumer applications.
